Hi,

The error message specks for it self : Connection refused

So, your OpenSER tried to open a TCP/TLS connection to an address where nobody was listening.

Hi... All ,

I have Configured OpenSER 1.3.2-tls source code & compiled successfully .

Registration is successful with TLS handshake .

Below is the scenario of my test .

UA1 & UA2 clients Registers on TLS.

When UA1 send INVITE request to UA2

I got the Following Error :

: SIP/2.0 477 Send failed (477/TM)

When i scanned through the logs of openser I got the following Message : proxy always trying to establish TCP connection but it Fails.

              - Presently i don't have any DNS server , is that 

really matters ?? - While openser tries to open TCP connection with UAS it's sending port ' 0 ' , but fails is it ok .?? , or Anything I'm missing in Configuration . I have Attahced config file Also.

Thanks & Regards, Pravin.swami
